Status:

Common and widespread (Terrell & Peterson, 2009).

Poverty Oatgrass is a dominant and widespread native species of oak-overstory savannah and glades. It forms a continuous turf with a lot of room for other plants (R. Simmons, pers. comm). This tough, perennial, native grass has the potential to replace non-native turfgrasses because it stays low; thrives in poor, rocky, thin, shallow, or compacted soil that receives little maintenance; is highly drought tolerant; and can grow in shade right up to a tree trunk. It grows in upland forests, woodlands, barrens, outcrops, roadsides, and other varied habitats (Weakley, 2012). Traditional lawn care practices, such as irrigation, fertilization, leaf removal, and use of pesticides, will kill it. Poverty Oatgrass has a mycorrhizal relationship that provides it with water and nutrients. There may be only a single mycorrhiza that can fill this role, and this relationship may take a while to develop on a site that is left undisturbed.

Description:

In winter, the blades of Poverty Oatgrass become curly and readily identifiable.

Relationships:

Host plant for Indian Skipper and Leonard's Skipper. A potential host plant for Common Wood-Nymph.
